Title: Flame-and smoke-resistant polyurethane foam and a method for producing the same
IPC: C08G18/32
Filed: 1976-05-14
Abstract: 1492246 Flame-resistant polyurethane foams BRIDGESTONE TIRE KK 14 May 1976 [15 May 1975] 20071/76 Heading C3R Flame- and smoke-resistant polyurethane foams are obtained by reacting a polyol; a polyisocyanate and from 3 to 40 parts by weight based on 100 parts by weight of the polyol of an amine-carbamate of a primary or secondary amine having at least one hydroxyl group in the presence of a surfactant and a polyol/polyisocyanate reaction catalyst. The amine-carbamate may be made either by dissolving the hydroxy-amine in a solvent, e.g. alcohol; passing carbon dioxide into the solution; filtering off the amine-carbamate crystals formed; drying and then suspending them in a polyol or by dissolving the hydroxy amine in the polyol and passing in carbon dioxide to form a suspension of amine-carbamate in the polyol. Suitable hydroxy-amines are monoethanolamine, mono-n-butanolamine, diethanolamine, di-n-propanolamine and N-(#-hydroxy ethyl)- ethylenediamine. In a typical example a flexible foam having a uniform cell structure is obtained by stirring together a suspension of the aminecarbamate of diethanolamine in a polyoxypropylene triol mol. wt. 1,000, a stannous octoate catalyst and a silicone surfactant, e.g. polydialkylsiloxane until homogeneous and then adding tolylene diisocyanate, allowing the mixture to react and form the foam after a rise time of 30 seconds.

Abstract: 1,043,693. Treatment of sugar beet seedlings. J. G. POTTIER. May 25, 1962 [Sept. 4, 1961], No. 20090/62. Heading A1E. A process for the modification of the biochemical characteristics of sugar beet seedlings comprises subjecting the seedlings to shock treatment at a temperature between -40‹C. and -197‹C. for a period of time less than 10 seconds. Seedlings freshly withdrawn from water are enclosed in a pinchbeck satchet lined with moist calico which satchet is then exposed to the required temperature, e.g. by immersion in crude liquid nitrogen, liquid propane or solid carbon dioxide, the satchet then being heated to ambient temperature e.g. by immersion in water. The treated seedlings are stated to produce beets of smaller height and therefore higher sugar concentration than untreated seedlings of the same strain and these dwarf beets also give dwarf beets in the second generation. A seedling is defined in the Specification as being a plantlet which has sufficiently out grown its parent seed to the extent of being capable of survival without being any longer dependent upon that seed.

Title: Improvements in circuits for central heating plants
IPC: F24D3/02
Filed: 1950-08-16
Abstract: 749,241. Heating buildings and hot water supply systems. CIALENTE, I. Aug. 16, 1950 [Aug. 16, 1949 ; May 16, 1950], No. 20342/50. Classes 64(1) and 64(2). In a central-heating plant, which may heat several buildings from one source, heat exchangers such as radiators or convectors 6 are mounted in series along a rising pipe 4 from a liquid boiler 1 to an open or closed expansion vessel 9 from which a downcomer pipe 12 returns to the boiler so that the hydrostatic head establishes in the rising pipe, at least at its lower portion, pressures greater than atmospheric so that some or all of the exchangers are operated with the liquid, e.g. water, at a temperature above its normal boiling point. A forced-feed device such as a pump 13 is included and the heat exchangers may be finned-tube or pipe-coil convectors in which the air flow, and thus the heat ouput, is controlled by a throttle, or they heat air which is passed over them by a speed-controlled fan. The heating may also be controlled by a byepass on each exchanger. Owing to the decrease in temperature progressively up the circuit with the decrease in pressure, the transmitting surface of the heat exchangers is reduced for those lower and nearer the boiler. Thermally or manually controlled throttling valves are included and to give more heat to the lower exchangers, e.g. on lower floors of a building to compensate for wind cooling, the water circulation is throttled. Where the rising pipe is inclined downwardly to avoid an obstacle an air blow-off pipe is provided to pass over the obstacle. Secondary heat exchangers 11, e.g. for heating water for washing &c., may be included in the downcomer pipe 12. Extra rising pipes 5 including heat exchangers 61 may be provided.
